How to Submit a Sample

sample

This page gives an overview of sample submission forms, fees, and shipping. It also gives instructions for collecting and packaging your sample.

Before you submit a sample, consider contacting your County Agent or a Master Gardener. He or she can diagnose many common plant disease and insect problems.

If necessary, the Agent or Gardener can help you properly collect and submit a sample to the PDIC. After the diagnosis, they can recommend control methods that are suitable to your location and situation.

Insects

Most insects - cockroaches, termites, bugs, beetles, flies, wasps, ants, maggots, spiders, etc. should be sent in ≥ 70% alcohol.

Mites, scales, aphids and thrips - send in alive on some of the affected foliage/stems, collected as you would a plant specimen. Place in a plastic bag when collected.

Butterflies and moths - send in killed (ethyl acetate is good, but can be killed in the freezer), packaged lightly in tissue paper in a crush-proof box.

Caterpillars - send in alive on some of the host plant in a plastic bag.

Grubs - send in alive in a pint or two of soil enclosed in a plastic bag.

When in doubt, put specimens in ≥ 70% alcohol and collect several specimens if possible.


INADEQUATE SAMPLES CANNOT BE DIAGNOSED!
